A music store sold 10 more cds on monday than tuesday. The total number of cds sold over the two days was 40. The number of cds that were sold on monday is 25 cds.

There were x cds sold on Tuesday. There were x+10 cds sold on Monday. There were 40 cds sold overall over the two days. So x+(x+10) = 40 is the equation you use.

Solving the equation,

x+(x+10) = 40, or

2x + 10 = 40, or

2x = 30, or

x = 15.

But on Monday, x+10 = 15+10 = 25 cds were sold.

But on Monday, x+10 = 15+10 = 25 cds were sold.

You stated to the user that you could not answer the question because you can not see the line. Then answered "The answer is A"

As a Weegy Expert, you must answer your questions accurately.

Also, asking the user "Is that all." is a little rude. Try "Is there anything else I can help you with?" or "Did you have another question?"
